﴿ثُمَّ أَنْزَلَ اللَّهُ سَكِينَتَهُ عَلَىٰ رَسُولِهِ وَعَلَى الْمُؤْمِنِينَ وَأَنْزَلَ جُنُودًا لَمْ تَرَوْهَا وَعَذَّبَ الَّذِينَ كَفَرُوا ۚ وَذَٰلِكَ جَزَاءُ الْكَافِرِينَ﴾
26. Then Allâh did send down His Sakînah (calmness, tranquillity and reassurance) on the Messenger (Muhammad ﷺ), and on the believers, and sent down forces (angels) which you saw not, and punished the disbelievers. Such is the recompense of disbelievers.
